The pyramidal eminence in the middle ear contains the:

• A Tensor tympani muscle tendon
• B Long process of the incus
• C Chorda tympani nerve
• D Stapedius muscle tendon ✓

Explanation

The pyramidal eminence is a hollow bony pyramid on the posterior wall of the middle ear. The stapedius muscle, innervated by the facial nerve (VII), emerges from the apex of the pyramidal eminence as a tendon inserting onto the neck of the stapes. The tensor tympani lies in a bony canal above the Eustachian tube and inserts onto the handle of the malleus. This is clinically relevant in facial nerve identification during mastoid surgery.
